Currently have my speakers set to small with the xover at 50 on the amp and just under on the sub. I find this gives me the tightest bass but plenty of low down action. Now, as my floorstanders allegedely go down only to 48hz, what's to stop me setting the speakers to Large and sub on Yes? What will happen in this scenario with a Pioneer AX5i? Will LFE from DVD still go to the sub in it's full glory? I ask as I may as well not use bass management with these settings. I've been experimenting lately with many different settings and in my room it seems a lower xover is best with the sub filling out the warmth. Also my Ruark Prelude R's have a very nice tight bass anyway. I'm connecting only with low level by the way.
